Apparently, you are using MingW features (user32 is a Microsoft library, not a POSIX one). So you should install the MingW packages. Here is a list; I doubt you need all of them, though (the exact set will depend on the application you are trying to build).
Try adding -L/lib/w32api (and maybe -I/usr/inclulde/w32api if your code includes "windows. H") to the gcc options.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
